Bonanza Billion Merge Up™+ at a glance
Bonanza Billion Merge Up™+ is a BGaming slot released on 24 September 2026 under the provider's #Entertainment label. It pairs the fruit symbols, bright colours and bouncy animations of the Bonanza Billion series with BGaming's Merge Up™ mechanics, and the provider says it was developed based on real player feedback.
The core idea is simple. Wins come from clusters of matching symbols, and instead of just vanishing, a paid cluster merges into a new symbol picked at random from those on the grid. Free Spins add multiplier symbols from ×2 to ×100, and Chance x2 and Buy Bonus offer quicker routes into the round.
Bonanza Billion Merge Up™+ RTP, volatility and max win
BGaming lists the RTP at 97.04% and rates the volatility as Very high. The maximum multiplier is published as x15000, and the spec sheet shows the top win as €255,000. The provider's FAQ gives the ceiling as up to ×15,000.
The spec sheet also shows a hit rate of 2.59 and an FS rate of 386.23, both without units or definitions, so we quote them exactly as BGaming gives them. The lines field reads Pays Anywhere.
According to BGaming, the route to the ×15,000 top prize runs through the Merge Up™ mechanics and the multipliers. Multiplier symbols only appear in Free Spins, so the base game relies on the merges alone.
How Merge Up™+ works
A winning combination is a cluster of 4 or more of the same symbol touching each other. Once the win is paid, the symbols in the cluster disappear and generate one random symbol chosen from the symbols present on the screen.
BGaming says this can raise the chance of a following win, because the new symbol may join others of its kind already on the grid. The page also refers to tumbling sequences, without describing them in detail, so the demo is the place to see how a spin plays out after a merge.
The randomness is the twist the provider highlights. You cannot choose what a cluster turns into: it might become the symbol that completes another cluster, or one that sits alone. BGaming does not publish the grid size or symbol pay values on its game page, so the in-game paytable is where to check what each fruit is worth.
Free Spins: 10, 20 or 30 spins
Free Spins are triggered by 4 or more Scatter symbols, or by buying the round. 4 Scatters award 10 spins, 5 award 20 and 6 award 30.
During the round, 3 or more Scatters add 5 more Free Spins. The retrigger threshold is lower than the trigger in the base game, where at least 4 Scatters are needed. As an illustration, a 10-spin round that retriggers twice runs for 20 spins in total.
BGaming's game page does not state a limit on retriggers.
Multipliers from ×2 to ×100
Multiplier symbols appear only in Free Spins. Each one takes a random value from ×2 to ×100 when it lands, and BGaming says they can appear randomly after tumbling sequences or come from merges.
When several multipliers land on the same spin, they are added together at the end of the spin and applied to the total win for that spin. As an illustration, a ×10 and a ×25 on one spin would give ×35, and a spin whose wins total 4× the bet would then pay 140× the bet.
Because the multipliers add rather than multiply, a spin with many small values can still produce a large combined figure. The base game has no multiplier symbols at all.
Chance x2 and Buy Bonus
Chance x2 increases the probability of activating Free Spins at a price adjusted to the bet. It is disabled while Buy Bonus is active, and BGaming does not state the exact bet increase on its game page.
Buy Bonus lets you purchase Free Spins during the main game at the price shown above the Buy Bonus button, and the price adjusts automatically when the bet changes. The provider's game page does not publish the purchase multiple or say how many Scatters a bought round starts with, so check the button and the game rules at your chosen stake before buying.
What to look for in the Bonanza Billion Merge Up™+ demo
The demo is the best way to see the merges without staking anything. Watch what each paid cluster turns into and how often that new symbol links up with others to form another cluster in the same spin.
In Free Spins, track how many multipliers land per spin and how their total compares with the win they apply to. BGaming says the game runs on smartphones, tablets and desktop. Slots are for adults aged 18 and over; set a time and spending limit before any session.
